About us
Who we are
FSTH Enerji Teknolojileri was founded by Assoc. Prof. Dr. Füsun Servin Tut Haklıdır, a geoscientist and energy systems academic whose career spans Zorlu Enerji's geothermal operations (Kızıldere, Alaşehir and exploration fields across Türkiye) and Istanbul Bilgi University. She serves on the IGA Standard Committee (since 2025), ETIP-DG (since 2017) and the European Commission's Horizon Europe evaluator pool (since 2022).
The company works with a network of specialist partners so that each engagement gets the right combination of reservoir, plant, digital and funding expertise.
FSTH Enerji is a research-intensive company. A large share of its work is applied R&D, carried out with universities and plant operators and shared through peer-reviewed publications where possible.

What we believe
Evidence before opinion
Decisions start from reservoir and operating data.
Field-to-plant
We never look at the subsurface without the plant, or the plant without the subsurface.
Deployable, not just publishable
Research is finished when an operator can use it.
